Mimulus cardinalis

Our wet monkey, Mimulus cardinalis, has started blooming. There are two kinds of monkey flowers, ones that like wet soil and ones that like dry soil. The dry monkeys (also sometimes called sticky monkeys, preferably with a faux-British accent) are starting to get listed as Diplacus, instead of Mimulus, which makes some sense to me, even though the switch also causes some confusion. There’s not really anything similar about the wet and dry types — not the foliage, the form, the habitat, the cultural needs, and not the flowers — so I’m not sure how they got grouped together in the first place. Las Pilitas has a page devoted to the various monkey flowers that talks about the differences. I’ve grown a few different types of wet monkey flowers, but the only one in our garden now is the scarlet monkey flower in our bog planting.

Colocasia Black Magic and Mimulus cardinalis

Our bog planting is set inside an old cast-iron bathtub dug into the ground and covered over with mulch. The idea is that the water drains more slowly than it would in open ground, so we don’t have to irrigate these water-loving plants as often as we would otherwise, a way to keep our garden low-water without excluding all the plants we’re interested in growing. We filled it with 2/3 soil and 1/3 compost, which is a ton of amendment by our standards. The only outlet from the tub is the open drain at the bottom and we water it the same amount and on the same irrigation zone as the moderate-water section of the yard where we have the blueberries, the mock orange, the heucheras, the astilbes, and our young citrus tree, plants that you wouldn’t normally expect to share an irrigation zone with a colocasia, which is often grown directly in ponds and fountains.

Black Magic stems

Colocasia “Black Magic,” aka Elephant Ears for its big leaves, is a very cool plant. It’s in the low part of our yard, so we don’t have a good view of the black stems, though the stems are my favorite feature of the plant, even more so than the leaves. We also have Yerba Buena (Satureja douglasii) and Yellow-Eyed Grass (Sisyrinchium californicum) hanging out under the colocasia, and a canna growing behind it. This is the third summer for the planting, and the colocasia has steadily increased, while the canna seems to be fading.

Stream Orchid, Epipactis gigantea

Last month the Stream Orchid, (Epipactis gigantea) was the main bloomer in the tub. It still has a few blooms, but it’s mostly finished now. Not a showy flower, but interesting up close.

Epipactis gigntea and Mimulus cardinalis

I feel like the scarlet monkey flower doesn’t even have the same color tone as most California natives. It’s more like the nasturtiums which come up as volunteers in our yard. A yellow one recently came up in the bamboo behind the bathtub, so we’re hoping it will ramble out into the monkey flower patch before the monkeys stop blooming. It’s a little surprising to me that a California native would combine so well with colocasias and nasturtiums, but I guess I should know better by now. Photos of wet and dry monkey flower buds (the one similarity I find between the two kinds), the yellow nasturtium, and a raunchy close up of the stream orchid are below. (more…)

Brodiaea

I’m a pretty loyal California native planter, but I had my confidence in one of the native bulbs, Brodiaea, shaken recently. We’ve been planting “Corrina” and “Queen Fabiola” for a couple of years, and they’re good small bulbs for our area — they have lovely blue flowers, they don’t take much space, and they don’t require any irrigation, you just fall-plant and walk away. But then a friend of mine said they looked like Agapanthus. Ouch.

agapanthus

That might not sound like a big deal to non-Californians, but around here agapanthus is the omnipresent strip-mall/sub-division/highway-median plant. Plenty of gardeners from other areas seem to like it — for instance, Garden Design magazine recently featured a French garden named Le Jardin Agapanthique, which to me is like naming it the Privet Garden — but it gets no love here. The flower is okay, I guess, but the foliage is too glossy for our landscape; it looks plastic and fake next to the more silver and gray foliage of other low water plants. I sort of respect the plant’s bomb-proof toughness — I once dug a bunch out of the ground and dumped it all in a pile in the sun in the middle of summer and three weeks later it was still blooming — but I’ve demoed a lot of it, and I find that it’s always heavy, it’s always full of snails, and it always leaves behind nasty wormlike white roots. My apologies to any agapanthus gardeners out there, but I don’t like it.

So it’s kind of disturbing to think that Brodiaea resembles agapanthus. Do other people see the similarity? There’s a photo of the Brodiaea foliage below, and, upon reflection, the leaves are actually kind of glossy, and the fact that they flop over and then turn brown doesn’t sound like much of an improvement over the agapanthus. But Brodiaeas are pretty. Maybe I like agapanthus more than I admit? I’ll still plant the Brodiaea — the Van Engelen catalogue just came, 100 bulbs for $10, such a deal — I just think I’ll have a faint touch of sheepishness when I see it in our gardens for a while.

Sidalcea malviflora, checkerbloom

Our Sidalcea malviflora (checkerbloom), grown from seed, surprised us when the different plants put out different shades of flowers. They’re just about done blooming for the year. We don’t water them, so they’ll go dormant and disappear at some point and then come back with the rains.

Paeonia californica, California peony

The California peony is blooming at the Regional Parks Botanic Garden at Tilden in Berkeley. I’d never seen one blooming before. To quote Las Pilitas, “You need perfect drainage, a very green thumb, and luck with this one.”

Allium unifolium

We’ve been starting to add California native bulbs to our home garden and our landscape plantings, and so far, Allium unifolium is one of our favorites. A lot of the native alliums require perfect drainage and a summer dry period and would be difficult to source even if you thought you could get the growing conditions right. A. unifolium, though, is easy to find and grow; we read that it’s supposedly the most clay tolerant of the alliums, and so far that’s been the case. Also, because it’s considered garden worthy (the Dutch like it) and not just for native purists, you can actually find it in sufficient quantities to make an impact in a large garden, where it will spread somewhat aggressively if it’s happy. It’s beginning to bloom in several of our gardens now.

Allium unifolium in our garden

We were recently at the Regional Parks Botanic Garden at Tilden for their native plant sale, and I took pictures of the alliums that were blooming. The bed’s aesthetic (three foot high bed of stone holding 4-12 inch high plants) is more for collectors than for casual visitors, but it has some interesting stuff, of which Allium crispum sounds like the best bet to try in a garden. The Pacific Bulb Society has a good info page for North American alliums. Far West Bulb Farm also has photos and info and might be a source for some of them. I put photos of four alliums and the raised bed below. (more…)

Indian paintbrush

Indian paintbrush is one of my favorite native wildflowers to see hiking, and one of the more unusual plants in any of our gardens. It is a hemiparasite, meaning it takes nourishment from a host plant but also photosynthesizes for itself. To grow it, you have to germinate the seed and then put it in a pot with another plant and wait for them to join root systems; when I read about the process, it sounded like a huge pain in the neck. Now that it’s established, though, it’s really carefree, growing with an Artemisia californica in some of the heaviest clay soil we’ve ever planted in. The two plants have similar foliage, so you don’t notice the paintbrush for much of the year, but then the blooms pop out from under the shrub and carry on for a long time before fading back and going dormant for the winter.

We got the plant at the Watershed Nursery, the only nursery I’ve ever seen selling it, and, in our experience, the best source for natives in the area. East Bay Nursery and Berkeley Hort and Annie’s Annuals are all good for natives, too, but they mostly sell cultivars and their plants come from all over the state, not really “native” in the purest sense. The Watershed Nursery, on the other hand, sells Bay Area natives, grown here in the Bay Area from seed collected here in the Bay Area. If you want to plant the same plants that you see when you’re out hiking, it’s the nursery to go to.

The paintbrush came in a gallon pot with the artemisia, but the Watershed Nursery grows most of their stock in restoration tubes. Restoration tubes, if you’ve never used them before, have some advantages over the typical gallon pots you find in the typical retail nurseries. Compared with a gallon-sized pot, it takes less time for the plant to fill the narrow tubes with roots, so the plant will cost less while still getting its roots just as deep in the ground, and the plants haven’t spent as much time in potting soil, so they are quicker to adapt to whatever soil you plant them in. The tubes have vertical ribs to keep the roots from girdling, and they are open at the bottom so the roots air-prune instead of circling the bottom or heading back up to the top. You don’t have to spend as much time undoing a root ball, so you can plant a lot more quickly, and you don’t do as much damage to the roots, so the plants establish themselves almost immediately. The plants look small when you first plant them, but they often seem to explode out of the ground. I’ve recently been passing by several yards where we planted a lot of Watershed Nursery plants, and they’ve all been looking big and healthy and happy. They have a sale every year during the upcoming Bringing Back the Natives Tour.
