Mistletoe has always been a bit of an enigma, and although it's a parasite on some of our native deciduous plants it holds such a serene beauty that it's captured the imagination of European cultures throughout the ages. Thankfully, as a native to the UK, it’s relatively easy to grow mistletoe from seed, but along with the decline of our fruit industry – the apple tree is one of its predominant host plants - the mistletoe is no longer as common as it had once been. But with a little effort, and a touch of patience, your garden may well provide the next host for this beautiful and enigmatic species.
To save leaving seed germination to chance, you can improve your germination rates by following these six tips for successfully growing mistletoe.
2. Harvest intact berries only, because if the berry skin ruptures the contents inside will harden hindering germination. Unfortunately germination rates for mistletoe seed can be quite low as only about 10% of their seeds survive to becoming a mature plant. With this in mind it's advisable to propagate at least twenty seeds, as when mature mistletoe will require both male and female plants to produce berries.
3. When choosing your host tree bare in mind the mistletoe's preferences – apples are first, then poplars, limes, false acacia, and then hawthorn. Occasionally they have been known to grow on oak.
5. Germination is fairly rapid and a short green hypocotyl (a growing tip which bears the embryonic leaves) should appear and bend to make contact with the host bark. At this stage these tiny plants are particularly susceptible to grazing invertebrates and birds. They are also prone to dehydration until their roots have connected with the hosts vascular system. If all goes well the hypocotyl will remain unchanged until the following February. Only then will a small new plant appear.
6. As the mistletoe develops the host branch will begin to swell in girth. Growth of this juvenile plant will remain slow taking five years to reach berrying-size. If either all male, or all female plants develop you can attach more seeds the mistletoe parent plant. Strangely mistletoe will readily act as a host to its own parasitic seed.
