Larger growing (Elepidote) Species Rhododendrons click here for the online catalogue
The elepidote Rhododendrons are most people's idea of the ‘typical' Rhododendron with relatively large leaves and large full trusses of flowers. The advantage of growing elepidote species is that they tend to have more interesting foliage than the hybrids: those with particularly good foliage are marked. It is important to realise that some species take many years before they start flowering, so you may need to be patient. Most of the species require shelter from winds and plentiful organic matter mixed into the soil for best results, though some species such as those in subsection Fortunea are pretty tough and easy. The spectacular large-leaved species are found mostly in subsections Falconera and Grandia. Most larger growing species are grown from wild or hand-pollinated seed. Those easily rooted are propagated from cuttings. A few are grafted as this is the only way to produce them. We use rootstocks such as ‘Cunningham's White' and R. decorum which seldom sucker and we never use R. ponticum.
Larger Growing but smalled leaved lepidote rhododendrons are covered here: Triflora
Hardiness We use divisions of hardiness which are adapted and improved from the R.H.S. hardiness bands. In the UK, it is rarely extreme cold that causes damage so don’t pay too much attention to minimum temperature ratings. Damage from late or early season frosts when plants are soft or not hardened off is much more common and can be very damaging or fatal. In continental Europe the minimum temperature ratings are more relevant.
H6 Hardiest, -240C (-100F) and below suitable for inland areas in N. Europe:
H5 Very hardy: -180C (00F) and below, coldest UK inland areas, amongst hills, much of N Europe.
H4 Hardy: Suitable for most of UK areas, including fairly well inland, coastal Europe.
H3 Fairly hardy: Low elevations and sheltered gardens, fairly near east coast. Limit of hardiness at Glendoick. Such plants are damaged in our severest winters or by late or early frosts.
H2 Rather tender. Low elevations fairly near west coast and on east coast. Not reliably hardy outdoors at Glendoick, though recent winters suggest that you may get away with them.
H1 Tender (mild frosts only). Mildest U.K. west-coast islands and western coastline.
