Yn gynnar bore Mawrth, roedd ardal Y Gerddi Botaneg Cenedlaethol Cymru yn symud gydag egni cymysg o gyffro disgyblion ysgol ar drip maes.

Early Tuesday morning, the area of the Gerddi Botaneg Cenedlaethol Cymru (National Botanic Gardens of Wales) was buzzing with a mixed energy of excited school children on a field trip.

Roedd yr awyr oer yn llawn arogl pridd a dail cwympedig, yn cuddio tân aur a choch yr hydref.

The cold air was filled with the scent of soil and fallen leaves, concealing the golden and red hues of autumn.

Mewn cylch bach, ymunodd Dafydd, Carys, a Rhys wrth i Miss Jones, yr athrawes dda ac huesog, esbonio'r diwrnod hir o ddarganfod iddyn nhw.

In a small circle, Dafydd, Carys, and Rhys joined as Miss Jones, the kind and lively teacher, explained the long day of discovery ahead of them.

Ond roedd calon Dafydd yn taro â drym bach gwahanol.

But Dafydd's heart was beating to a slightly different drum.

Roedd ganddo rywbeth arbennig iawn yn ei feddwl – planhigyn prin a ddarllenodd er's tro, ond na welodd erioed.

He had something very special on his mind—a rare plant he had read about long ago but had never seen.

Roedd y planhigyn hwnnw yn llechu, yn ôl ei ymchwiliad, rhywle yn y goedwig lysieuol o'i gwmpas.

According to his research, that plant was lurking somewhere in the surrounding herbal forest.

Y problem oedd – nid oedd amser nac anadl goll ar i ffwrdd o'r grŵp.

The problem was—there was no time, nor breath to be wasted straying from the group.

Gerllaw, croesodd Carys a Rhys eu llwybrau ger Cwrt Y Stablau, lle dywedwyd wrthynt am ddelweddau gorthrymedig o wyddoniaeth a natur oedd i ddod.

Nearby, Carys and Rhys crossed paths near Cwrt Y Stablau, where they were told about the intriguing images of science and nature that awaited them.

Roedd Rhys yn rhedeg yn gyffrous ymlaen, ond bu Dafydd ar ei ôl, yn anghyffro a phwysig.

Rhys ran excitedly ahead, but Dafydd lagged behind, unenthusiastic and preoccupied.

Nid oedd yn hawdd i droi ei feddwl oddi ar y planhigyn hudoliaethus oedd yn dal ei ddychymyg.

It wasn't easy to divert his mind from the enchanting plant that held his imagination.

Wrth i'r grŵp gymryd egwyl byr o dan pawisenna trymion y dail, roedd Dafydd wedi penderfynu.

As the group took a short break under the heavy boughs of the leaves, Dafydd made a decision.

Oni bai ei fod yn mynd nawr, byddai'r cyfle marwol wedi diflannu.

Unless he went now, the fleeting opportunity would disappear.

Fe lyfodd ei ddechrau wrth osod ei draed ar lwybr i ffwrdd, ei gysgod yn lluwch ar lawr moch y coed.

He took a deep breath as he set his feet on the path leading away, his shadow cast like a cloak on the forest floor.

Daeth pob cam â echdoriadau cyffrous o gyffro a braw.

Every step brought bursts of excitement and fear.

Roedd y gerddi'n ymestynodd o'i flaen, llawn perllannau aur a gwyrddlas, a heulwen yn dod trwyddo fel trawst yn doriadau'r coed.

The gardens spread before him, full of golden and green orchards, with sunlight piercing through like beams in the gaps of the trees.

Yn sydyn, ymddangosodd y planhigyn ble roedd wedi gobeithio am – Planhigyn Pelydryn Hyll y Coedwig.

Suddenly, the plant he had hoped for appeared—"Planhigyn Pelydryn Hyll y Coedwig" (Ugly Grace Plant of the Forest).

Roedd yn ei weld yno, bychan ac ychydig â lliwiau prin iawn a gleiniau dŵr bore ar ei ddail.

He saw it there, small and with very faint colors, with morning dew beads on its leaves.

Roedd hyn oll yn ysgwyd meddyliau Dafydd, ond yna llais dewr a pharabl ei flaen ef.

This all captivated Dafydd's thoughts, but then a bold voice and speech ahead of him.

"Beth t'i'n wneud yma, Dafydd?

"What are you doing here, Dafydd?"

" gofynnodd Rhys, a'i lygadluseithau ar y planhigyn.

asked Rhys, his eyes widened in awe at the plant.

Roedd Llygaid Rhys yn fawreddog â siâr gwir o eddrych mewn ciwir.

Rhys's eyes were noble with a true share of admiring sincerity.

Am eiliad, cael Dafydd yn gafael yn yr exceitio difrifol pan ddarganfododd ef rhywbeth a llemeth Rhys yn seibianc.

For a moment, Dafydd grasped the intense excitement when he discovered something and invited Rhys to take a pause.

Roeddwn y wahodd ddiedrych i'r ciae ein gilydd– darganfod planhigyn anhygoel.

It was an invitation to look deeper into one another's passions—to discover an extraordinary plant.

"Gawn ni ddangos i'r athrawon?

"Shall we show the teachers?"

" gofynnodd Rhys, ei alwad yn syml a ffyddlon.

asked Rhys, his request simple and sincere.

Roedd Dafydd, gyda gwen deheuig, yn cytuno.

Dafydd, with a clever grin, agreed.

Daeth ennyd rheini â newid i alegaid Dafydd – i newid ei oleuni ar fywyd a chyfranogi'n rwysg i wirionedd ddangos y mae cael diddordeb a bywiog mewn rhywbeth ond yn gyfrwng i gyfnoedig.

Those moments brought a change to Dafydd's vision—to change his understanding of life and to enthusiastically participate in the truth that having interest and enthusiasm in something is a bridge to connection.

Ar ôl hynny, daeth Dafydd a Rhys yn gydymaith annisgwyl yn eu antur i gyhuddio'r athrawes ac eraill o'r planhigyn a'r buddugoliaeth technegol wnaethon nhw.

After that, Dafydd and Rhys became unexpected companions in their adventure to inform the teacher and others about the plant and their technical triumph.

Yn y gerddi dan lanw hydref, roedd y cyfeillgarwch yn datblygu yn ei ddawn ac yn ei gryfder danddadleol.

In the gardens under the autumn tide, their friendship developed in its talent and undeniable strength.

Roedd pob cam oddi ar y llwybr yn troi eu datguddiad ar bethau newydd, ac yn edrych ymlaen at gynnesad dwyfolrwydd prifder trothwy'r haf arall.

Every step off the path turned their revelation into new discoveries, looking forward to the divine warmth of the next summer's threshold.
