We recommend visiting our subtropical greenhouse to see 𝘊𝘢𝘯𝘢𝘳𝘪𝘯𝘢 𝘤𝘢𝘯𝘢𝘳𝘪𝘦𝘯𝘴𝘪𝘴: these captivating colours come out best in real life! ⁠
⁠
🪶The Canary Island bellflower is known locally as 'bicácaro'. It's pollinated by passerine birds, such as the chiffchaff. ⁠
⁠
⁠

Sliding into the weekend like...⁠🐌⁠
⁠
🍀𝘚𝘮𝘺𝘳𝘯𝘪𝘶𝘮 𝘱𝘦𝘳𝘧𝘰𝘭𝘪𝘢𝘵𝘶𝘮 or perfoliate Alexanders blooms with bright yellow-green flowers in spring. ⁠
⁠

⁠
Did you know that the colours of the hortensia are determined by pH levels of the soil? Ideal pH levels for each shade are as follows:⁠
⁠
💙= below 5.5⁠
💜= between 5.5 and 6.5⁠
🤍= between 6 and 6.2⁠
💗= over 7

... As promised in our previous post: you were looking at the curiously shaped seed of the 𝘚𝘵𝘳𝘦𝘭𝘪𝘵𝘻𝘪𝘢! Commonly known as bird of paradise flower or crane flower. ⁠
⁠
🧡In our Palm Greenhouse you will find 𝘚𝘵𝘳𝘦𝘭𝘪𝘵𝘻𝘪𝘢 𝘫𝘶𝘯𝘤𝘦𝘢. In the wild, the plant relies on sunbirds for pollination. ⁠
⁠
🐦️The sunbird will perch on and drink from the spathe. The weight of the bird when stending on it, will open the flower up to release the pollen onto the bird's feet: which then carries it to the next! ⁠
⁠

🤡So, here's a fun one!🤡⁠
⁠
🍊This happy little ball of orange fluff is actually a seed! ⁠
⁠
❓️Can you tell us what species this seed belongs to? ⁠
⁠
👀Stay tuned, we will reveal the responsible plant tomorrow...

The swirling remains of 𝘐𝘱𝘰𝘮𝘰𝘦𝘢 𝘱𝘶𝘳𝘱𝘶𝘳𝘦𝘢, or purple morning-glory. ⁠
⁠
🪜Like all morning glory species, this plant entwines itself around structures, growing to a height of 3 metres tall. ⁠

💛Hawaiian lily, cup of cold vine or golden chalice vine: a few describing common names of the 𝘚𝘰𝘭𝘢𝘯𝘥𝘳𝘢 𝘮𝘢𝘹𝘪𝘮𝘢. In our tropical greenhouse you can find this species climbing up the wall.⁠
⁠
😍It has very large yellow flowers and there are still many buds waiting to open.

🧡The absolutely stunning 𝘉𝘳𝘶𝘨𝘮𝘢𝘯𝘴𝘪𝘢 𝘢𝘶𝘳𝘦𝘢 or golden angel's trumpet can now be seen in bloom in our Palmhouse! It spreads a lovely fragrance, which is strongest in the evening.⁠
⁠
☠️Brugmansia species are amongst the most toxic of ornamental plants. All parts of the plant are highly poisonous and contain a high concentration of the psychoactive scopolamine. ⁠
⁠
🥴Parts of the plant have been used as a 'truth serum': this species is also known as 'borrachero' which loosely translates to 'get-you-drunk'. ⁠

"In winter, we struggle with the lack of sunlight and being inside a lot but this place really gave us the green boost we needed."⁠
⁠
Lovely words by Hortus visitor @theblightynomads! Thank you💚⁠
⁠
🙌🏼Come visit our garden this weekend if you're feeling a little under the weather. Plants will cheer you up!🍃

The stunning flowers of Baker's aloe (𝘈𝘭𝘰𝘦 𝘣𝘢𝘬𝘦𝘳𝘪) in our desert greenhouse. Its flowers are very attractive to birds, bees and wasps. We can see why they're so loved! Look at these colours.🌈⁠
⁠
The species is native to Madagascar and unfortunately critically endangered in the wild.

In our tropical greenhouse you can still spot the unique flowers of 𝘈𝘳𝘪𝘴𝘵𝘰𝘭𝘰𝘤𝘩𝘪𝘢 𝘢𝘳𝘣𝘰𝘳𝘦𝘢. ⁠
⁠
🏵️The flowers usually appear in small groups at the base of the stem (cauliflory) with single or paired flowers a bit higher up in the leaf axils. They form an insect trap - just like other species of the genus Aristolochia. ⁠
⁠
🐝💨The pollinators are held for a day, during which they become covered with pollen. After the flower withers, the insect is released!

This star flower (𝘖𝘳𝘣𝘦𝘢 𝘷𝘢𝘳𝘪𝘦𝘨𝘢𝘵𝘢) is thriving in our desert greenhouse! ⁠
⁠
👃🏼Star flower (or 𝘚𝘵𝘢𝘱𝘦𝘭𝘪𝘢 𝘷𝘢𝘳𝘪𝘦𝘨𝘢𝘵𝘢, its older name) is also known as carrion flower, because this pretty looking flower has the odor of rotting meat to attract pollinating flies. ⁠

💚These curly ferns look like they're in the middle of a conversation.⁠
⁠
🐣Ferns are a hardy plant species. In winter, the fronds will protect the plant's center crown, where new growth will emerge in spring.

Sometimes even the leaves in our tropics look autumnal! ⁠
⁠
🍂🧡Enjoy your weekend and don't forget to go out and explore some nature.

Another look at the strange and spiky thorn apple (𝘋𝘢𝘵𝘶𝘳𝘢 𝘴𝘵𝘳𝘢𝘮𝘰𝘯𝘪𝘶𝘮). Now ripened, it's ready to cast its seeds! ⁠
⁠
🧹In early times, the thorn apple was considered an aid to the incantation of witches. The extremely poisonous plant was also considered a bringer of bad luck for anyone who grew it in their garden.
