New growth and missed opportunities

As mentioned in the previous post the last month has been extremely wet in Denmark. Some of my plants seem to thrive in the humid environment and are setting new growth while the plants just about to flower haven’t exactly rejoiced in the rain.

Last year I planted 4 Opuntia compressa (Monmouth County, New Jersey) seedlings in one of my beds. The plants were started from seed in 2004 (Mesa Garden described the plants as “cold and wet – no problem” in their catalogue, and they are head-on). The new cladodes are still a fresh lime-green and are bearing reddish-brown leaves.

At the age of 3 the plants are setting their first flowers – I’m hoping for some sun for the flowers to develop properly.

I’ve had my Opuntia 'Smithwick' plant for several years and it never felt like flowering – until now. Unfortunately many of the flowers haven’t fully developed because of the weather and have ended up as “duds”.

Still others have been maimed by gastropods (snails, slugs, what have you) wallowing in the rain.

Budding spring - Rhodiola and Opuntia

My Rhodiola rosea plants are coming out of winter in great shape. A couple of years ago I collected a handful of rhizomes from habitat in Greenland and now grow the plants in an unprotected bed along with my hardy cacti. The Rhodiola rosea plants originate from the hills above Hospitalsdalen (Hospital Valley), a place named after an American military hospital built in connection with the Bluie West One airfield during the 2nd World War. The hills are situated a few kilometers north east of Narsarsuaq and from the top you have a direct view of the Greenland Ice Sheet – I guess the location says it all regarding the plants cold tolerance ;-)

I’m a bit curious as to whether I have both male and female plants; when I dug up the rhizomes I didn’t know the plants were dioecious, so even though they were flowering at the time I didn’t pay attention to their sex.

Allegedly Rhodiola rosea is categorized as an adaptogen with various health-promoting effects (like e.g. Panax ginseng), but I have no experience with these aspects of the plant.

My Opuntias are also breaking out of dormancy and beginning to set new growth, as illustrated by the pictures below.

Opuntia and Cylindropuntia – new growth

After a couple of weeks of almost summer-like temperatures in Denmark the Opuntia species growing in my unprotected bed has resumed growth.

The ever trustworthy Opuntia 'Claude Arno' cultivar is bursting with budding cladodes.

Opuntia 'Smithwick' is also a survivor, coming out of winter dormancy with great vigor.

My Opuntia polyacantha also lived through winter without damage.

Finally the Cylindropuntia imbricata plants growing in pots protected from the worst precipitation are much better off than the C. imbricata in the unprotected bed.
