Choosing the best alstroemerias

Choosing the best

To get the best, choose clear colours , not the dingy, half shades, that you so often see in their cellophane wraps as cut flowers.

There are various dwarf forms (the Little Miss series), where the proportion of flower to stem is all wrong and they look rather like a chubby little pony covered in rosettes.

Go instead for the 2ft-plus varieties. I also like the ones such as Alstroemeria 'Friendship', HRH Princess Alice and 'Adonis', where the individual flower stems are long once they branch at the top. This makes them more rangy and elegant and avoids any dumpy, over-stuffed feel.

Why you should grow the newly-bred hybrid alstroemerias...

Growing alstroemerias from the newly bred hybrid types – developed by people such as the late James Smith with his Princess series, Parigo in Spalding and the breeding program of Mark Bridgen at the University of Connecticut – will give you magnificent plants. Like dahlias, these are tender tubers, growing alstroemeria has become much easier with our increasingly mild autumns and winters.

If you plant them deeply - with 4in-6in of soil on top of the tubers, so they're below the normal soil frost level - and mulch the clumps to protect them, most will reliably over-winter outside. Hardiness used to be a problem with some species and earlier-bred hybrids. They would start to shoot in April and would then be cut down by frost, which would knock them right back. But these modern early-flowering varieties such as 'Apollo' are made of sterner stuff. If frost cuts this one back, it just comes straight up again.

Unlike earlier hybrids, many of the recently bred varieties aren't three-week wonders either, the ones that flower only once in July, then die down, leaving you with a gap. The remarkable thing about many of the modern varieties is that they flower for months at a stretch, pumping out three or four separate flushes of flowers. And unlike the ligtu hybrids and some of the species (such as A. aurea), they don't seed everywhere and become invasive. After settling in for a couple of years, the new varieties spread slowly below ground, little by little, but not enough to become a pain - perfectly behaved, in fact.

We stock these new varieties of alstroemerias, sent out ready for planting straight away from April through to early summer. See our full range of alstroemeria plants.
