Kris,

I do nothing except some fertilizer in spring!

Frosts down to -18C, this year a new summer record with 37,5 C, no watering ever! Linz has close to 800mm rain/year, most of it in the summer months! No reliable snow cover!

I will be glad to exchange next summer!

My best clone of Sternbergia sicula.....


Beautiful clumps Herbert!
It certainly is a very floriferious clone! How is the flowering after a colder summer?

According to a recent study, you can't. See:

Botanical Journal of the Linnean Society, 2011, 166, 149–162

Too large to post but available online.

The abstract for this paper says :

Abstract/Summary
The phylogenetics of Sternbergia (Amaryllidaceae) were studied using DNA sequences of the plastid ndhF and matK genes and nuclear internal transcribed spacer (ITS) ribosomal region for 38, 37 and 32 ingroup and outgroup accessions, respectively. All members of Sternbergia were represented by at least one accession, except S. minoica and S. schubertii, with additional taxa from Narcissus and Pancratium serving as principal outgroups. Sternbergia was resolved and supported as sister to Narcissus and composed of two primary subclades: S. colchiciflora sister to S. vernalis, S. candida and S. clusiana, with this clade in turn sister to S. lutea and its allies in both Bayesian and bootstrap analyses. A clear relationship between the two vernal flowering members of the genus was recovered, supporting the hypothesis of a single origin of vernal flowering in Sternbergia. However, in the S. lutea complex, the DNA markers examined did not offer sufficient resolving power to separate taxa, providing some support for the idea that S. sicula and S. greuteriana are conspecific with S. lutea.

Sternbergia lutea flowering in my garden. The flowering is much better than usual due to a warm and dry summer.
