Among the particularly resistant annual plants that reach medium heights and therefore also ideal for growing in pots, there is certainly Nemophila. It is also important to underline that this specimen belonging to the Boraginaceae family, in the growth phase, is of great use to set up rock gardens or to delimit their borders. Particular characteristics of its flowers and minimal maintenance make Nemophila one of the most appreciated plants by gardeners.
The plant with the botanical name Nemophila is native to California and in particular to its bay area, although it grows well in many other regions with a mild climate. Opting for this specimen means creating a spectacular bed of soft blue or white flowers which among other things also attract important garden pollinators. Butterflies, bees and other beneficial insects use its nectar as food. Having said this, it should also be added that the Nemophila being a shrubby plant with low diffusion with stems and flowers with six curved blue petals, it is suitable as part of a garden cultivated with other specimens of the most varied pastel shades. The plant is also easy to grow and requires very little care.
Nemophila is easy to grow starting from seed. Specifically, just choose a sunny area or in partial shade and possibly sheltered from the wind. That said, it should also be added that the plant prefers sandy and grainy soils and has a certain tolerance to drought. In fact, light sandy loam makes for a better seedbed as it performs excellent drainage. Keeping it slightly moist until germination is however essential for optimizing the result intended in terms of luxuriant growth of this specimen. The plant, as previously mentioned, does not require special care, and does not need fertilizers if grown in areas with a soil already rich in organic substances.
Diseases and treatments
Diseases and parasites are rarely present in Nemophila as it is a specimen that does not live long enough to attract the main threats represented by aphids and fungal spores. Although it is an easy plant to grow, there are nevertheless two problems that are worth paying attention to. The first is to avoid excessive irrigation; in fact, if the leaves get too wet they could irremediably die. The second, on the other hand, concerns the removal from plants prone to mold since Nemophila could also develop it. If this condition occurs, the plant must be removed to prevent the problem from spreading to other specimens.
Apart from its botanical name with a clear Latin imprint, the Nemophila also boasts a colorful nickname in relation to the soft blue color of its flowers; in fact, the plant is commonly called blue eyes. The bluish flowering of this specimen, among other things, manifests itself quickly, so much so that the first specimens appear within about six weeks of sowing.
