Signs of Life

Like winter’s frosty mornings, time can seem frozen still at this time of year. Dark mornings, cold days and bleak grey skies seem to dominate and give little hope of spring ever arriving. But now February is well under our belts, a few days of good sunshine has lifted our spirits and brought some welcome signs of spring.

In the top courtyard pots, some dwarf bulb species are beginning to flower. Iris histrioides ‘George’ (AGM) has a particularly attractive rich maroon colour and this delicate little daffodil, Narcissus ‘Spoirot’ is a hybrid seedling from N. bulbocodium subsp. Bulbicodium var. conspicuus and N.cantricus subsp. Cantabricus var. foliosus, raised during the late 1980’s at Glenbrook bulb farm in Tasmania by a Mr. Rod Barwick. Not until 2011, did the RHS give it a well-deserved award of garden merit.

The winter aconites, Eranthis hyemalis (AGM) which have been flowering since mid-January never fail to lift the spirits. But, it is not until their bright yellow faces get some proper sunshine that they really begin to open fully and light up.

Yesterday while we inspected our snowdrop collection, of which we have around 18 different varieties/species according to our records, we also began a debate about Crocus tommasinianus.

Sometimes referred as the ‘Snow crocus’ and one of the earliest corms to flower. Crocus tommasinianus was named after a botanist and the Mayor of Trieste, Muzio.G.Tommasini. It is native to Bulgaria, Hungary and the former Yugoslavia.

As you can see it has become prolific and has seeded itself extensively throughout the Lime walk and into the Nuttery. It is creating some controversy, because while on mass it does attract much admiration by volunteers and private guests to the garden during our closed time, it also has become cause for some concern. Tommasinianus has become a thug; a bully whose deep rooted corms and subsequent mat forming roots are in danger of out competing the healthy growth of neighbouring bulbs, which need all their strength to establish and flower at their best.  Left unmanaged, I think it could engulf the whole garden eventually.

So what do we do next?

Our solution is to be stricter from now onwards. We must remove runaway seedlings which appear elsewhere in the garden, dead head to stop further seedling invasions and when areas of the Lime Walk are added to, we will try to remove as many crocus corms from the soil as possible.

Before I dampen all our spirits again, by talk of invasive plants, here’s a pretty picture of a completely different character. This is the lovely orange coloured witch hazel, Hamamelis x intermedia ‘Arnhem.’ Unlike the speed in which the aforementioned crocus takes over, this shrub is slow growing and minds its own business. It was a gift given to us in 2010 and in a year or two will branch out a bit more.

  1. Thanks for sharing – bulbs look fantastic! Such a shame about the thuggish behaviour of the Crocus tommasinianus – it makes a great show. I find a lot of the best & easiest performers in the garden are the thugs and we gardeners get seduced by the display. But in 3-4 years a once ‘mixed bed’ of succession planting, is dominated by one plant. Given I live in Northern NSW Australia, it’s nice to see these thugs that I can’t grow!

    • Hi,
      Ooh, glad you have enjoyed seeing our display, despite our mixed feelings on their success. You are absolutely right, it is the invasive plants that are initially so quick to establish that can sometimes cause the most work! Good luck with your gardening activities. Jo

  2. It’s such a shame about the thuggishness of the Crocus, as they do look spectacular. One thing that might help limit its spread is by burying those inexpensive flexible garden edging rolls (they are commonly sold in large Hardware chains here in Australia, I assume large garden centres in the UK would stock them) into the soil to demarcate Crocus areas from non-Crocus areas. As long as it is 20+cm high, It will limit the spread of the corms/roots and you’ll still be able to keep naturalistic ‘drifts’ on one side of the edging without actually seeing the edging….together with the dead-heading it should contain the thug 🙂

    • Hello,
      Thanks for your comment amd suggestions. I can see that an invisible barrier could help to limit the spread of the aforementioned crocus. In this case, I think it is their spread via seed which causes us the most trouble and due to the density of bulb planting in Lime Walk, it is difficult to isolate any individual group of bulb species (particularly when it is so invasive), without affecting other bulbs which may actively be encouraged to spread more. We will simply have to keep a eagle eye on them. Do follow our progress.
      Regards, Jo.
