Fresh seed appears to be important. One batch of seed kept refrigerated for several months did virtually nothing. A second batch planted straightaway gave about 50% germination within 45 days.

Young potted plants have fared well in this hot southern summer when given a mix of peat and perlite, adequate moisture, and a location with direct morning sun.

I was surprised and delighted to find that two cowslips I planted over a decade ago have prospered here in Boston Z6a with little care. They're very showy in bloom. They bloom well, and haven't suffered too badly from the slugs.

They're in dappled shade all day. The soil is a heavy acid silty urban mess, in a raised bed, with some organic amendment, and only watered sporadically during droughts. Though the books recommend frequent division, I have yet to divide either clump after 12 years.

I've never seen a self-sown seedling, but I don't know if that's due to site conditions/climate or to having two plants that can't cross-pollinate.

I was surprised by how well these have done, despite my negligence. They aren't often grown around here.

Bluestone Nursery sold this to me under the name "Cabrillo". It looks just like this and is a Primula. It is wonderful and so cute. It came up right away in early spring and started blooming last week. The blooms are really opening up now and growing taller each day. They are around 6" tall now. They look real healthy. I couldn't find anything on them under the name "Cabrillo", but when I searched the titsy-tosty sites, I saw this and it looks just like mine. I'll have to take a picture and figure out how to post it.
I live in a very cold, windy site and had tons of snow this winter and it did great.

A variable, evergreen perennial from Europe.

Has slightly hairy rosettes of oblong-ovate, scalloped or toothed, mid green, wrinkled leaves. Bears drooping, yellow sometimes with orange spots at the base of the lobes, scented, funnel shaped flowers on one side of the flower stem and a light green conspicuous calyx.

The flower colour can vary from light yellow to deep red in cultivated forms.

Flowers April-July.

Likes a well drained, moist, fertile, lime soil in full sun or light shade.

Superb woodland or wild garden plant and will reward you with many seedlings if happy.

Can irritate sensitive skin.

Children used to suck the nectar from the flowers and the scent is a little like cow's b... read more
