 Glyn Bach Gardens  (Gerddi Glyn Bach)



BGB_Tiranti copy (1)



Glyn Bach Gardens holds a National Collection of Monarda; these beautiful plants grow well in the warm, wet,  climate of West Wales.  They are used throughout the garden to provide colour, form and nectar for our diverse and plentiful population of long tongued bumble bees.


Didyma species are usually red in colour and grow best in damp conditions.


Fistulosa species are the largest grouping and are white, pink and purple predominately; these grow in drier conditions.

Monarda have real impact in a perennial border or in prairie planting schemes.


They originate from the East coast of America and are really classed as a woodland edge plant so the flowers tend to last longer in semi shade;  in full sun the flowers fade more quickly, although still reasonably long lasting.


Mildew is a problem when Monarda are stressed; this is usually when they are too dry at the roots, as they are moisture lovers.  In West Wales, this is not an issue, but gardeners in the East of the country should be aware that Monarda will need watering, with rainwater preferably, in times of drought.



Piet Oudolf has been instrumental in developed more mildew resistant cultivars.  The horoscope range are reasonable, with Pisces being a Glyn Bach favourite. All cultivars containing the suffix Lace  are beautiful and worth growing:-  Pink Lace, Sugar Lace, Cranberry Lace and Purple Lace.  


Any Monarda which is purple or white coloured are usually fistulosa crosses so tolerant of drier conditions.

The essential oil components of the leaves have been used to determine genetic relationships between species (Scora 1967).


Plants of a given species from different geographical regions may, however, yield strikingly different oils. Monarda fistulosa L., native to the Canadian prairies, is drought tolerant, winter hardy, and may yield an essential oil high in geraniol content (Marshall and Scora 1972; Mazza et al. 1987).


When this native species is crossed with M. didyma, vigorous hybrids, yielding essential oils rich in geraniol, linalool, thymol, carvacrol, 1,8-cineole, and other terpenes can be produced. In the present study, the content and composition of the nitrogen extracted volatiles and hydrodistillated oils from eight winter-hardy, powdery mildew, and rust-resistant hybrids were determined, with the aim of developing new alternative crops for Canadian agriculture.


Geraniol     - natural alcohol which attracts bees but repels mosquitoes

Linalool     - terpene alcohol which produces scent, insect repellent and    

                     downstream vitamin E

Thymol     -   antiseptic and preservative

Carvacrol  -  inhibiter

Cineole      -  expectorant – expels mucus from respiratory tract infections

Monarda is native to the USA and was well known to the Native Americans for its health giving properties.
